Existing studies have often failed to find positive impacts of horizontal FDI on domestic firms. We argue that the two effects underpinning the impacts of horizontal FDI (i.e., the positive spillover effect and the negative competition effect) have different degrees of attenuation with geographic distance. As FDI is often distributed unevenly across space, studies that do not account for the ge...

We numerically investigate the epidemic spread phenomena and efficient immunization strategies on complex networks embedded in geometry. It is assumed that there exists an unavoidable time delay (we call it the detection time) between the actual infection and the beginning of immunization, and we implement two different immunization strategies: one is based on topological connection neighbors (...

The value of using otolith chemistry to characterize recruitment in terms of natal source regions depends on how consistently spatio-temporal variation can be resolved. The objective of this study was to compare regional classification patterns in the otolith chemistry of juvenile Spotted Seatrout (Cynoscion nebulosus) between two years experiencing disparate hydrological regimes, and separated...

The paper analysis the role of the Internet for different types of innovation not only focusing on the traditional set of product, process, organizational and marketing innovation, but also extending to innovation in the public sector. In addition to the role of the Internet for various types of innovations, it has also implications for new forms of innovation, especially for the new paradigm o...

Résumé. L’image médicale 4D représente une succession d’images volumiques sur l’axe temporelle, ce qui représente une énorme quantité de données à compresser afin de la stockée ou de la transmettre. Dans cet article, nous présentons une technique de compression d’images médicales 4D basée sur le SPIHT3D. Cette technique applique la transformée en ondelettes 3D afin d’éliminer efficacement les r...

In the 1970s, some people believed in using computers for making almost any information available to anyone and for supporting information exchange and discussions regardless of geographical distances. These ideas were, at that time, novel and revolutionary. Some people regarded these ideas as dangerous; for example, the Swedish Data Inspection Board (Datainspektionen) forbade people from stori...

We report a study of a collaborative human-robot system composed of a science team (located in Pittsburgh), an engineering team (located in Chile), and a rover (located in Chile). The project was intended to be analogous to and inform planetary exploration. We performed observations simultaneously at both sites over two weeks as scientists collected data using the rover. We observed problems in...

The ubiquitous availability of broadband Internet connectivity at home is driving the use of the Internet for entertainment and other forms of recreation. Paving the way for many demanding multimedia applications over IP, it has accelerated the emergence of new ideas for network-centric collaborative work that was impossible only a few years ago for both technical and economic reasons. Among ma...

Coordinating software tasks across geographic locations is difficult because of factors like: limited opportunities for interaction, lack of contextual references, and leaner communication media. Team cognition research suggests that team knowledge helps members coordinate because they can anticipate task issues more accurately, communicate more efficiently and find expertise within the team, a...

This paper presents an overview of the field of distributed development of software systems and applications (DD). Based on an analysis of the published literature, including its use in different industrial contexts, we provide a preliminary analysis that structures existing DD knowledge, indicating opportunities but identifying threats to communication, coordination, and control caused by temp...
